In a door or window lock there is a rower which can be rotated with a handle and which is at least partially made of a somewhat elastic substance, for example plastic. In the rower 1 there is a substantially square hole 2, which is intended for the square pin 11 of the handle and is somewhat undersized in relation to the cross section of the square pin, and, close to this hole, an elastic region which springs out of the way when the square pin 11 is fitted. This elastic region comprises the limit surface of the hole 2 and at least one, preferably at least two, cavities 7, 8 situated close to the limit surface. <IMAGE> |
